APEX and BRS dosing pumps HELP.

[Bio14guy]

Ok, So I'm trying to redo my programming for my apex so i don't dose all in one shot i want to spread it out over a few hours. This is my current ALK program.

Fallback OFF
If Time 07:30 to 07:39 Then ON
If Time 07:39 to 07:29 Then OFF
If pH > 8.35 Then OFF


I want to spread out the dose from 01:45 to 18:30 Im dosing about 10ml per day. any help would be great.

you would be better off using an osc code. i believe those pump run 1.1ml per min. Here is an EXAMPLE. you need to adjust the ( OSC 000:00/000:30/059:30 Then ON ) so the last two settings only run the pumps during your desired time frame to add the amount you request. You'll need you pump rate to do the math.based on a 1.1ml pump the above code would come on for 30 seconds each hour. Since you want it on for 18 hours the code below would add 9.9ml per day.

I'm guessing your pump rate so please verify these numbers prior to use!!!

Fallback
